HIGH GLOSS METAL EFFECT PAPERS AND BOARDS
20180058009 · 2018-03-01 · ·

The instant invention pertains to a method for the production of brilliant glossy metal coatings on paper or board substrates. Further aspects of the invention are a paper or board product obtainable by using the method and the use of such a paper or board for decorative or packaging purposes. In particular the instant invention is directed to a method, wherein a UV curable composition is applied/printed on a paper or board substrate and cured through the paper or board from the reverse side by UV/Visible light. Simultaneously with the curing step the coated/printed paper or board is pressed from the coated/printed side against a mirror like shim. The shim has no structure and should be of mirror quality. In a second step this glazed and cured surface is overcoated/overprinted with an aluminium layer. The result is a metallized surface exhibiting excellent gloss and brilliance.
